冠心病心肌梗死后心肌细胞不能再生或再生能力极弱,导致具有收缩功能的心肌细胞减少,最终发展为心力衰竭,目前对冠心病的治疗手段都不能解决心肌细胞再生的问题,冠心病病死率仍居高不下,随着分子生物学技术的发展,移植外源性干细胞替代受损心肌细胞的治疗策略得到人们越来越多的关注。干细胞是一类具有自我复制和多向分化能力的不成熟
Coronary heart disease after myocardial infarction myocardial cells can not regenerate or very weak regenerative capacity, resulting in decreased systolic myocardial cells, the ultimate development of heart failure, the current treatment of coronary heart disease can not solve the problem of myocardial cell regeneration, coronary heart disease mortality Remains high. With the development of molecular biology techniques, more and more attention has been paid to the therapeutic strategies of transplanted exogenous stem cells in replacement of damaged cardiomyocytes. Stem cells are a type of immature with the ability to self-replicate and to differentiate
